How to measure the resolution time of single-channel pulse amplitude analyzer
The steps are as follows:

1. Input a pulse signal with a certain frequency from the pulse generator to the single channel, and adjust the size of the discrimination threshold to make the single channel in a critical trigger state.

2. Record the size of the screening threshold. Change the frequency and record the corresponding discrimination threshold.

3. Draw this set of data, and get the relationship diagram between discrimination threshold and pulse frequency.

4. Find out the range of threshold drift on the graph, and the counting rate of single channel is the largest.

5. When the counting rate is maximum, record the corresponding resolution time.
